My ears were ringing.
Hendrikjansen - I would skip the Tiablo line at this point; Take a look at the Olight M20 or LumaPower MRV SK. The LED Lenser P7 is pretty attractive as well. The Olight M20 is like your TK20 - but 'more' - output, features, etc.
Marduke & yalskey:
The new LED Lenser HP line should not be compared to their old product. The HP line cannot be seen at mass market stores like Costco and other similar retailers.
To make a judgement on an entirely new product line that you've not seen, basing judgement upon old product that you've only seen briefly or on a concensus opinion also based upon outdated information is simply illogical.
Yes - LL has an odd way of measuring runtime but 'output to 50%' is not some universal standard outside of CPF. There is an advisory panel of flashlight industry folks trying to put together a 'universal standard' which LL is a part of so one assumes that their runtimes will be more in line with the norm but remember none of the other mfr's, except those that cater to CPF, even tell you WHAT their runtimes are based upon.
Regarding battery choices; yes, I'd like to see a LL CR123A powered light but that doesn't mean AA's and D's don't have their place. They are cheap and widely available, especially in Europe where LL is based. I had a long conversation with the owner and chief engineer of LL and while they weren't 100% sold on a wholesale conversion they did seem open to testing the waters with some CR123A powered models so perhaps we'll see something coming in the future.
The LL HP line's quality is far beyond anything made by Dorcy. The HP line offers adjustable focus, something rarely seen on the flashlight market, esp with LED's and it's very easy and fast to adjust focus from spot to flood. Are they an enthsiasts light? Yes, I believe that some of the models are entirely legitimate entrants for the enthusiast market - if I didn't we would not have picked up the line.
